Scene: Armin's Jealousy

After a long training session, the group has dispersed. Mikasa and Eren are chatting in the distance, while Jean had just been talking to Mikasa for a good portion of the afternoon. Now, Armin is sitting alone on a stone bench, arms crossed, staring at the ground with a frown.

Jean approaches, hands in his pockets, looking a little hesitant.

Jean: “Hey, Armin. You’ve been sitting here for a while. Something up?”

Armin: (without looking up) “No, I’m fine.”

Jean: (raising an eyebrow, crouching down slightly to meet Armin’s gaze) “Yeah, right. You’ve got that ‘I’m fine but actually, I’m mad’ tone. What’s going on?”

Armin: (shrugs) “It’s nothing. Just tired, I guess.”

Jean: (sits down next to him, bumping his shoulder lightly) “C’mon, I know you better than that. You’re sulking about something. Did Eren say something dumb again?”

Armin: (shakes his head, voice quiet but slightly sharp) “It’s not about Eren.”

Jean: (leaning back, genuinely confused) “Okay, then what is it? You’ve been weird ever since—” (pauses, realization dawning) “Wait, is this about earlier? When I was talking to Mikasa?”
